Function that stays on when a value is at one state

Help and Feedback Scripting Support
#1

How would I go about making a function that only runs when a value is at a certain state? For example, say I want to make an energy system. I want the energy to only regen when it is not sprinting. I tried using a while loop, but it didn’t work.

It very much depends on what you’re making, for the sprinting system you mentioned, you can use something like this:

local sprinting = false
local energy = 100

local ENERGY_DECREASE_RATE_WHILE_SPRINTING = 3 -- per second
local function turnSprintOn()
        sprinting = true
        task.defer(function()
                while sprinting do
                        local dt = task.wait()
                        energy -= ENERGY_DECREASE_RATE_WHILE_SPRINTING * dt
                end
        end)
end

local function turnSprintOff()
        sprinting = false
end

It’s basically event driven code, that when you start sprinting, it’ll keep ticking down the energy until you stop sprinting

something like this, but please, learn basic scripting, this isn’t too hard:

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local UIS = game:GetService("UserInputService")

local RunningSpeed = 30
local CurrentStamina = 100
local IsRunning = false

local function UpdateStamina()
	while true do
		task.wait(0.1)
		if IsRunning and CurrentStamina > 0 then
			CurrentStamina = CurrentStamina - 1
		elseif not IsRunning and CurrentStamina < 100 then
			CurrentStamina = CurrentStamina + 1
		end

		if CurrentStamina <= 0 then
			IsRunning = false
			Humanoid.WalkSpeed = 16
		end
	end
end

UIS.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.LeftShift and CurrentStamina > 0 then
		Humanoid.WalkSpeed = RunningSpeed
		IsRunning = true
	end
end)

UIS.InputEnded:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.LeftShift then
		Humanoid.WalkSpeed = 16
		IsRunning = false
	end
end)

task.spawn(UpdateStamina)

For example, have a bool value set as an instance inside the same script doing the energy/sprinting. After that, just update the value each time the player is sprinting. Apply the :GetPropertyChangedSignal and check if its true or false. If sprinting is false, do the regen loop with an external bindable connection saying that it will break on .Event.
Here is an example:

local Bindable = Instance.new("BindableEvent")
Value:GetPropertyChangedSignal("Value"):Connect(function()
     if Value.Value == false then
         while true do
              task.wait(regen_time)
              --Do regen stuff here:
               Bindable.Event:Connect(function()
                    break
               end)
         end
     else
          Bindable:Fire()
     end
end)

idk if this would work. Might contain some syntax errors or some stupid stuff I forgot to check :rolling_eyes: But try it out! :slight_smile: (I might be overcomplicating this, but it gave a basic idea of the script structure you need)

I don’t exactly get the necessity of a BindableEvent if you aren’t using it between scripts, or the necessity of a BoolValue over just a variable

This code will also leak memory a lot

I was able to get all the hard stuff like the actual running script (with tweens for fov and everything!) and yet I can’t do this lol.

Break down everything into smaller chunks, or write pseudo code, solving a problem is combining small chunks to complete a bigger one, like a puzzle basically.
